Organization Sub System

  1. 1. ORGANISATION SUBSYSTEM Lekshmi.S
  2. 2.  A management information system is essentially an integration of information systems that are designed to support the functional systems of the business.  Information systems which developed around the functional areas of a business organisation are popularly known as Functional Information System.  Each of these functional areas requires unique information. Thus it requires a support of information system framed specifically for it.  MIS ( an integration of information system ) is designed to support the fuctional subsystems of the business
  3. 3. Subsystems of an MIS Two approaches :  Organizational Function Subsystems  Activities Subsystems
  4. 4. Organizational Function Subsystems There may be common support system used by more than one subsystem, but each functional system is unique in its procedures,programs,models,etc.  Production/Manufacturing Marketing  Personnel  Logistics  Finance & Accounting  Information Processing  Top Management
  5. 5. Activities Subsystems  Transaction Processing – Processing of orders, shipment and receipts.  Operational Control – Scheduling of activities and performance reports.  Management Control – Formulation of budgets and resource allocation.  Strategic Planning – Formulation of objectives and strategic plans.
  6. 6. System is the 3rd element of MIS.It is an inter related set of elements that functions as a whole. A system may be defined as a set of elements which are joined together to achieve a common objective. The elements are inter related and inter dependent. In an information system, data are input which is processed to convert it into information. When feedback and control elements are attatched to any system ( to make it self – regulatory and self monitoring ), it is known as Cybernetic System.
  7. 7. INPUT PROCESS OUTPUT
  8. 8. Open & Closed system Super system & Sub system Deterministic & Probabilistic System
  9. 9. Open & Closed System A system which does not interact or exchange any of its inputs or outputs with its environment. Eg: A chemical reaction in a sealed , insulated container. A system which interacts with its environment and exchanges inputs is called Open system. Eg: Biological system (such as humans ) and organizational systems.
  10. 10. Super system & Sub system Some systems are part of a large system and they are known as sub system. They are interactive and dependent to each other. They work together to achieve a common goal. Eg: Human body – respiratory system, nervous system Super system is a large and complex system. it may or may not have a number of parts known as its subsystem. Super system is always complex and difficult to understand. Eg: Education System
  11. 11. SYSTEM
  12. 12. Deterministic & Probabilistic System A deterministic system is one in which the occurrence of all the event is certain or it is a system which operates in accordance with predefined set of rules. Every step and order of their performance is known. Eg: Billing System of a departmental store A probabilistic system is one in which the occurrence of the event cannot be perfectly predicted. The results of such system cannot be pre-determined. Eg: Examination system, Sales forecasting, Weather forecasting.
